[Sony Xperia P, U, Sola, Go] temes:
You could select "Cyber-shot™ 4.7.2", copy (CTRL+C), then paste (CTRL+V) to XDA search field, press enter, then click first link. Easy right?

I have 3 xperia models (X10 Mini Pro rooted-unlocked, Xperia Mini Pro rooted, and Xperia U rooted) tried dozens of ROMs on them, but never had any problems like you. Why? I don't flash something what I don't know how it's work, what will it do. I tried to explain that, but you didn't hear me. I tried to help not to brick your device, because I think you don't have the proper knowledge for messing with your system such deeply. When I rooted my first device, I searched and read about rooting and flashing for weeks. And when I did the root, I knew everthing about the rooting process, the modifications what rooting does, and about restoring my device to its original state. The problem is, you don't know these informations. You unlocked your bootloader, and threw away the only easy way to repair your device is something goes wrong. Even you don't use the benefits of your unlocked bootloader. You don't want to use custom kernel. Yes, you want to use memory tweaks. But do you know what memory tweaks does with your phone? Because I don't. But I will never flash it. So you'd better to learn some basic information, because we are messing with android's protected files and partitions. And this is not too safe, even if you don't know what you are doing.

About thanking. I think devs deserved our thanks. This would be the first, and if remains some, they can be taken by other users for their posts.

Anyway, I think, you didn't thanked me 8 posts today, so you can give one to Rizal Lovins if you want... Or at least to Divaksh...

For this ROM version, 7000+ downloads and only 22 thanks. Not too motivating to make a new version...

About helping. I never helped in questions what answered thousand times in this thread, just wrote "search and read". I thought I can try to change and try to help. But it was a mistake. If new users get answers easily, they don't have to read and learn, just execute the answers without understanding what they are doing. The result is your state. You faced with a problem, but you didn't know what caused it. You don't know how managed to work your device again. You don't know why don't work kernels what many people are using without any problem. And first of all, you don't know what to do if your phone doesn't start.

The answers for all of these problems are simple. But you have to read and understand what changes you make with flashing a rom/kernel/mod, otherwise you never can use your device as you like.

edit (answering your edited post):

1. you have no usb drivers on your windows pc for mass storage (again, read and learn...). You can copy to internal storage with normal usage, with data cable or over wifi. Just copy somehow the zip to your internal storage (named in file system as sdcard). Doesn't matter how.

2. I have cybershot v.6.0.0, experimental version with small changes to 5.7.2, can be found in cybershot thread posts, not in first post.

My phonebook sometime lags 5-10 sec, but this is because of B.1.54 fw and because I have all of my facebook contacts (not only with numbers) with photos in my phonebook. This is the only lag, all other apps runs flawlessly.
